sql查詢基於月結束日期生成月薪日期

我想基於一個月的「月薪」和「月末」日期生成月薪日期。假設我選擇了「01/26/2016 「作爲」支付日期「和」01/31/2016「作爲」月末「日期和日期範圍是2016年。然後，」月末「日期將是該年的月份的最後一天和支付日期將在2016年全年的其他月份爲（「月末」月份日期 - 月「」的「付款日期」）。我添加了支付日期「01/26/2016」和「01/31/2016」作爲「月末」日期。我的SQL版本是2012. 我想知道SQL中的查詢。sql查詢基於月結束日期生成月薪日期

任何幫助將不勝感激。

截圖爲「2016年2月8日」爲「支付日」和「2016年1月31日」爲「月末」

基本上你需要得到**的時間差**所選月份的最後一天**和**選擇的支付日期之間的**和應用**與其他月份相同的差異**。這是你的要求嗎？ – Viki888

正確@ viki888 –

同樣的邏輯與last question。

您可以按以下：

DECLARE @StartDate DATETIME = '2016.01.26' 
DECLARE @EndDate DATETIME = '2016.01.31' 

SELECT 
    DATENAME(dw, A.Month) DayNameOfMonth, 
    A.[Month], 
    DATENAME(dw, A.[Pay Date]) DayNameOfPayDate, 
    A.[Pay Date] 
FROM 
(
    SELECT 
     DATEADD(DAY, -1 - (DAY(EOMONTH(@EndDate)) - DAY(@EndDate)), DATEADD(MONTH, v.m, DATEFROMPARTS(YEAR(@EndDate), 1, 1))) 'Month', 
     DATEADD(DAY, -1 - (DAY(EOMONTH(@StartDate)) - DAY(@StartDate)), DATEADD(MONTH, v.m, DATEFROMPARTS(YEAR(@StartDate), 1, 1))) 'Pay Date' 
    FROM 
     (VALUES (1), (2), (3), (4), (5), (6), (7), (8), (9), (10), (11), (12)) AS v(m) 
) A

結果：

DayNameOfMonth     Month  DayNameOfPayDate    Pay Date

修訂

DECLARE @StartDate DATETIME = '2016.01.31' -- month end 
DECLARE @EndDate DATETIME = '2016.02.08' -- pay date 

SELECT   
    DATEADD(DAY, -1 - (DAY(EOMONTH(@StartDate)) - DAY(@StartDate)), DATEADD(MONTH, v.m, DATEFROMPARTS(YEAR(@StartDate), 1, 1))) 'Month End',   
    DATEADD(DAY, DATEDIFF(DAY, @StartDate, @EndDate), DATEADD(DAY, -1 - (DAY(EOMONTH(@StartDate)) - DAY(@StartDate)), DATEADD(MONTH, v.m, DATEFROMPARTS(YEAR(@StartDate), 1, 1)))) 'Pay Date' 
FROM 
    (VALUES (1), (2), (3), (4), (5), (6), (7), (8), (9), (10), (11), (12)) AS v(m)

更新2

DECLARE @StartDate DATETIME = '2016.01.31' -- month end 
DECLARE @EndDate DATETIME = '2016.02.08' -- pay date 

SELECT 
    * 
FROM 
(
    SELECT   
     DATEADD(DAY, -1 - (DAY(EOMONTH(@StartDate)) - DAY(@StartDate)), DATEADD(MONTH, v.m, DATEFROMPARTS(YEAR(@StartDate), 1, 1))) 'Month End',   
     DATEADD(DAY, DATEDIFF(DAY, @StartDate, @EndDate), DATEADD(DAY, -1 - (DAY(EOMONTH(@StartDate)) - DAY(@StartDate)), DATEADD(MONTH, v.m, DATEFROMPARTS(YEAR(@StartDate), 1, 1)))) 'Pay Date' 
    FROM 
     (VALUES (1), (2), (3), (4), (5), (6), (7), (8), (9), (10), (11), (12)) AS v(m) 
) A 
WHERE 
    YEAR(A.[Pay Date]) = YEAR(@EndDate)

感謝您的回覆，但如果我輸入'2016.01.31'作爲「月末」日期和'2016.02.08'作爲「付款日期」，則輸出與我期望的結果不符。 @NEER –

@GopalBiswas請問您能展示想要的結果嗎？ – NEER

請參閱編輯的問題@NEER –

試試這個

DECLARE @PayDate AS DATE = '2016-Jan-26', @MonthEndDate AS DATE = '2016-Jan-31' 
DECLARE @Start AS INT = 0, @End AS INT = 11 
DECLARE @DateDiff AS INT = (SELECT DATEDIFF(DAY, @PayDate, @MonthEndDate)) 

; WITH CTE AS 
(
SELECT @Start as number 
UNION ALL 
SELECT number + 1 
FROM CTE 
WHERE number < @End 
) SELECT 

DATENAME(dw, DATEADD(MONTH, number, @MonthEndDate)) + ', ' + convert(varchar(12), DATEADD(MONTH, number, @MonthEndDate), 113) AS MonthEnd, 
DATENAME(dw, DATEADD(DAY, [email protected], DATEADD(MONTH, number, @MonthEndDate))) + ', ' + convert(varchar(12), DATEADD(DAY, [email protected], DATEADD(MONTH, number, @MonthEndDate)), 113) AS PayDate 
FROM CTE 

/* Output: 
MonthEnd     PayDate

只有一次更改需要「PayDate」應該在一年內。請參閱已編輯的問題@Tanjim Rahman –

您所要求的只是簡單的邏輯更改，可以在'@ DateDiff'的某些條件下完成。 – Esty

DECLARE @Y int = 2016; 

SELECT RD.ME MonthEnd, RD.PD PayDate FROM 
(select 
1 as mth 
union 
select 2 
union 
select 3 
union 
select 4

select 5

select 6

select 7

select 8 
union 
select 9 
union 
select 10 
union 
select 11 
union 
select 12) M 
CROSS APPLY (SELECT DATEADD(month, M.mth - 1, DATEADD(year, @y - 1900, 0)) RM) OA 
CROSS APPLY (SELECT DATEADD(day, -1 , DATEADD(month, 1, OA.RM)) ME, DATEADD(day, -6 , DATEADD(month, 1, OA.RM)) PD) RD ORDER BY RD.ME
